1 Claim. ((1211-62) This invention relates generally to, jalousie windows, and more particularly has reference to a Window of this type so designed as to include an improved connector tit swingable between closed and selected open positions.. In a typical installation, the jalousie window-may in ac tuality comprise a plurality of sets of slats, that is, the window opening may be divided at uniform intervals by mullions, and the provision of these structural members in turn divides the large window opening into a plurality of side-by-side, individual, smaller openings.

In each of these openings a set of jalousie slats is mounted, with all the slats of the set beingconjointly swingable between closed and selected, open positions.

The present invention aims to provide an improved means for connecting all the slats of one'set with allthe slats of an adjacent set at the other side of a mullion that separates the two slats, with the connection being such as to permit conjoint operation of both sets.

In other words, the invention aims to provide an im- 1 proved connection, extending directly throughthe dividing mullion or equivalent separating member, which will permit operation of a gang of jalousies, up to perhaps six sets, by a single cranking mechanism-and operation.

Another object is to provide a structure of the character stated that will permit the desired connection to be made at a very low cost, through; the provision'of a very simply designed, inexpensive connector plate particularly designed for providing a fixed connection between the vertically shiftable, jalousie-operating rods of adja-,-

cent sets.

Another object is to so provide the connection between adjacent sets that the mullion or equivalent separator will itself provide a guide for the connecting device, during the up-and-down movement of said. device.

Another object is .to provide a construction ofthe character stated wherein the connector is so designed that .one can use the same only when it is desired-to connect-sideby-side sets for conjoint operation through themedium of a single. cranking mechanism,.that is, thewconnector meansds selectively usable or not usable, as desired, and when not. used,'the sets may: be mounted" for individual operation.

Other objectswill appear from the following description, the. claims appended thereto, andflfrom the annexed drawing, in which'like referencecharacters designate like parts. throughout theseveral'views, and wherein:

Referring to thedrawingin detail, designated generally et -10 is a jalousie window according to the present in- :vention, the illustratedt window. being of the multi-unit or gangtype, having a-plurality of like units or gangs 11 of jalousies. At oppositesides of the window 10 there are provided side'jamb assemblies 14, 'while" as a sep aratorcbetweenlthe gangs 11 there is amullion 15. To simplify. theillus'trationand description, only two gangs arefshowna.However,ithetinvention is applicable to a substantially greater'number of sets or gangs, of course.

The present invention, in thisconnection, is intended to comprise an improvement: upon the-construction covered in my Patent 2,607,585. Therefore, there being certain detailsof construction. in. the present case that are similar to those in vthe.zpatent,-no needis seen to describe all detailsinthepresent case: Instead, it will be understood that where afull description of construction details is not provided; herein, and where said details are like those in thei'construction covered by the named patent, the description in saidpatent will be considered as applying to the present case.

In any-event, thewindow includesthe usual sill 16 common. tothe several gangs, and: the usual header 12,

alsocomrnon to the several gangs, these being connected between the lower and-;iupper .ends, respectively, of jambsv 14."

The window is mounted in any type of building wall,

and byway of illustration there is shown a building wall including a panel: 18 facing interiorly of the building. There-.wouldalso be a panel facing exteriorly of the building, the exterior panel being shown only fragmentarily and :being designated at 19. The cross sectional. configuration of the side jambs and mullion may vary, as may also the materials of which theseaare. formed; These may be formed of wood material eitheraof solid or hollow cross section. Alternatively,.1they may be of extruded metal shapes, sheet metal, etc.

In the illustratedexample, the side jambs 14 are of sheet metalbent to shape, as shown in Figure 3, said side jambs including vertically extending members having undercut front and backwalls22 adapted to receive the plaster or other finishing material of a wall W. The front and back walls have shallow'recesses or insets 24, receiving jalousie assembly support strips 26. Strips 26 have insets 28 intermediate the.front.and bacl edges of the strips, and the strips, along .one. longitudinal edge, have channels '30 forthevertically slidable operating bars, to be described in detail hereinafter.

It will .be understood thatthe support strips extend substantially. the full length of the side jambs, as clearly shown in Figure 1, that is, thefull height of the slat assembly. This is to provide a guide surface of maximumnlength for the operating. or connecting bars of the slat assemblies, duringthe swinging of the slats between their normally closed positions shownin Figure 2 and open positions shown in Figure..3.

The mullion can be of wood,v and of either solid or hollowv cross. section. In the illustrated example, the mullion is a hollow, sheetmetalnmember, formed of a painof vertically.extending,.interfitted side sections 32, 34 the: :opposite longitudinal edges. of which have offset flanges that are .interengaged andrthat. are fixedly secured in any. suitable :mannenzto provide the mullion.

At both sides of the mullion, there are provided opposite but identical, shallow recesses 36 analogous to the recesses 24. Recesses 36 receive, at the respective opposite sides of the mullion, oppositely but identically formed jalousie assembly support strips 38, which are disposed in confronting relation to their associated strips 26, as will be seen from Figure 3.

Strips 38 have insets 40 in confronting relation to the insets 28, and have channeled portions 44 similar to the portions 30.

Vertically slidable in the channels 30, 44 are operating bars 46, 48. These may be formed of channel -metal material, and formed in the respective operating bars are openings 50. The openings 50 of each bar are arranged in a straight row extending longitudinally and centrally of the bar, with the openings of each row being uniformly spaced over the full length of the row.

The openings 50 define, in cooperation with the unperforated portions of the bars occurring between the openings, rack teeth, so that in efiect, each bar 46 or 48 constitutes an exceedingly inexpensively formed rack, adapted to mesh with gear segments of the jalousie slats, in a manner to be described in detail hereafter.

A single operator mechanism 52 is provided for the several gangs 11, this being the result of the particular connecting means to be described in detail hereafter. Operator 52 need not be described in detail, since it is basically conventional. It is sufficient to note that the operator includes a hand crank 54 journalled in a bearing mounted in the building wall. Crank 54 rotates a worm 56 in mesh with a gear 58. Gear 58 rotates a shaft to which is secured a flat, toothed disc or gear 62, the teeth of which are adapted to enter the openings 50. Therefore, on rotation of the crank in a selected direction, the bar 48 in mesh with gear 62 will be caused to move upwardly or downwardly.

As will be seen from Figure 1, only one of the operating bars is extended downwardly below the sill, this being the operating bar that is in mesh with the gear 62. The remaining operating bars are vertically slidable in their associated channels 30 or 44 as the case may be, and are perforated as at 50 similarly to the bar appearing in Figure l.

The several jalousie slats of each gang 11 are designated 64, and when in closed position (Figure 2) overlap at their top and bottom edges to provide an effective closure for the window opening. The uppermost slats at this time bear against a header or upper stop 66, while the lowermost slat bears along its lower edge against a lower stop 68 mounted upon the sill.

Each slat, at its opposite ends, is engaged in slat-retaining brackets 70, formed as channels receiving the ends of the glass pane or other material of which the body of the slat is formed. The brackets 70 are pivotally mounted at 72 upon the respective strips 26 or 38 (Figure 3) for swinging movement between the closed, Figure 2 positions and the open, Figure 3 positions.

At their inner ends, brackets 70 are integrally formed with gear segments 74 (Figure 2), the teeth of which extend into the openings 50 of the adjacent operating bars 46 or 48. The toothed periphery of each segment is curved about the axis of the pivotal movement of the slat, as will be understood.

Further, said toothed periphery is tangential to the line of straight line movement of the operating bars 46, 48.

Therefore, on up-and-down movement of the operating bars of any gang, the slats thereof will be caused to pivot about their axes, between a closed position and selected, open positions.

In accordance with the invention, all the gangs are conjointly operated, by the single operator 52.

To this end, there is provided a plurality of identical gang connector plates 76. These are shown in Figures 4 and 5 to best advantage, and a number of said plates is provided to connect each pair of adjacent gangs, al-

though a single plate 76 could connect side-by-side gangs or units 11. The several plates 76 used to connect a single pair of adjacent gangs are spaced vertically of the mullion 15, as shown'in Figure 2, and as will be noted, each plate 76 is formed from a single piece of flat sheet metal having the requisite rigidity and strength, the shape of the plate being that of an I. Thus, each plate includes a vertically elongated, wide body portion 77 integral at its upper and lower ends with cross members 79. The opposite ends of each cross member project laterally outwardly beyond the opposite sides of the body portions 77, forming projections 78 each of which has an opening 80.

The projections 78 overlie and are in contact with the operating bars 48 disposed at opposite sides of the mullion 15. The body portion 76, thus, is disposed directly inside the mullion, with the projections 78 slidably engaging in and projecting through vertical guide slots 81 formed in the opposite side walls of the mullion.

The mullion thus constitutes a guide for the vertically shiftable gang connector plates.

The projections 78 are secured to the operating bars 48 by means of screws 82 extending into selected openings 50 of the operating bars. Therefore, it will be apparent that the connector plates can be secured to the operating bars at any desired location along the length of the operating bars, since openings 50 are closely spaced over the full length of said bars.

In any event, it will be apparent that once a pair of operating bars, disposed at opposite sides of a mullion, are connected by one or more connector plates 76, said bars will be caused to be conjointly movable upwardly and downwardly.

Therefore, on rotation of crank 54, all the gangs will be simultaneously operated. This is so because vertical movement of the bar 48 in mesh with gear 62 will necessarily cause conjoint vertical movement of the other operating bar, disposed at the opposite side of the mullion. The slats themselves of course necessarily require that all other vertically extending bars in mesh with segments 74 move upwardly or downwardly, and thus conjoint movement of as many as six or even more sets of jalousies results.

The construction has decided advantages over conventional arrangements, since it reduces considerably the number of the parts heretofore involved. Previously, to

provide for conjoint operation of gangs of jalousies, there have been utilized sleeves, shafts, sprockets, etc., as shown, for example, in the above named patents.

It is believed apparent that the invention is not necessarily confined to the specific use or uses thereof described above, since it may be utilized for any purpose to which it may be suited. Nor is the invention to be necessarily limited to the specific construction illustrated and described, since such construction is only intended to be illustrative of the principles, it being considered that the invention comprehends any minor change in construction that may be permitted within the scope of the appended claim.

What is claimed is:

A jalousie window for mounting in a window aperture, comprising: a plurality of vertical frame members spaced horizontally of and within said aperture and cooperating to divide the same into a plurality of gang-receiving openings; a gang in each opening comprising operating bars mounted on the frame members at opposite sides of the opening for vertical movement, slats pivoted on and extending between said frame members, the slats being interengaged with the operating bars to effect pivoting of the slats responsive to vertical movement of the operating bars; means engaged with at least one operating bar of the jalousie window for imparting up-and-down movement to said one operating bar; and means connecting adjacent operating bars of adjacent gangs for 'conjoint up-and-down movement, comprising at least one connector plate secured to and extending between said adcentrally extending rows of openings, the slats engaged 10 with said adjacent operating bars having gear segments the teeth of which extend into said openings to produce pivotal movement of the slats responsive to up-and-down movement of the operating bars, said connector plate having openings in its respective side portions registrable 15 with selected openings of said rows, for extension of fastening elements through the registered openings to connect the plates to the adjacent operating bars at selected locations longitudinally of the operating bars.
